' To all whom it may concern -Be it known that I, EDWARD AUGUST APPELL, a subject of the German Emperor, and a resident of the cityA of New York, borough of the Bronx, inthe county and State of New York, have invented a new and lmproved Liquid-Measuring Device, of which thefollowing is a full, clear, and exact description.

The object of the invention is to provide a new and improved liquid measuring devicemore especially designedfor measuring liquids periodically drawn from a barrel or other container. p

In orderto accomplish the desired result use is made of a valve casing providedwith an inlet and an outlet for the fluid and adapted to be connected with the container containing a liquid to be measured, a valve mounted to turn in the said valve casing and having sets of inlet and outlet ports, actuating and measuring devices connected with the said valve casing to be filled and emptied either with the liquid withdrawn from the container or with the air flowing into the container or withdrawing the liquid therefrom, the said .actuating devices having movable members under the influence of the pressure of the fluid passing into and out of the actuating and measuring devices, and driving means connecting the said movable members of the actuating and measuring devices with the said valve for imparting a continuous rotary motion to the same on withdrawing a'portion of the liquid from the container.

A practical embodiment of the invention is represented .in the accompanyin drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the liquid` measuring device for measuring the liquid flowing out of its container and through the measuring device;.Fig. 2 is a sectional side elevation of the same vsubstantially on the line 2 2 of Fig. 1; Fig. 3 is an enlargedpartl-y sectional plan view of the valve and connections, the section being on the line 3-3 of Fig. 2; Fig. ltis a similar v view of the same showing the valve in a different position; Fig. 5 is a similar view 'of the same on the line 5 5 of Fig. 2; Fig.

6 is a reduced sectional side elevation of the 7 use is made of two measuring receptacles A and A in the form of cylinders, in which reciprocate pistons B, B Connected, as hereinafter more fully described, with the stem C of a rotary valve C mounted to turn in a valve casing D located between the measuring receptacles A. and A. The valve casing D is provided with an inlet pipe E connected with a barrel or other vessel containing the liquid t0 be measured, and the outlet pipe E is connected' with a draw-oli3 faucet (not shown) under the control of a barkeeper or other person for drawinfr oli' periodically any desired amount of the liquid into a glass or other vessel.

The valve casing D is provided at the rear with an inlet chamber D (see Figs. 3 and 4) connected with the supply pipe E'and the valve C is provided with a series of inlet ports a, a, a2, as arranged in the Jform of a cross, as plainly shown in Figs. 3, 4 and which the pipes F and F2 connect with the inner ends of the mea'surirg receptacles A.

and A', while the pipes F and Fs connect with the outer ends of the said measuring receptacles A and A.

The valve C is further provided with a set of angular outlet p orts b, b', '52, 53 adapted to connect with the pipes F, F', F2 and F8 at the'time the inlet ports a, a', a2 and aa are disconnected fron; the same, and the said outlet ports b, b', b2 and b3 discharge into an outletchamber D2 formed in the bottom f of the valve casing D and connected with the outlet pipe E. It is understood that the outlet ports b, b', b2 and 7a2 are arranged intermediate the ports a, a', a2 and a2', as will be readily understood by reference to Figs. 3, 4 and 5.

The means for turning the valve C from the pistons B, B are arrangedas follows: The piston rods B2 and B3 of the pistons B and B extend through the outer heads of the measuring receptacles A and A', and the outer ends B4, B5 of the said piston rods B2, B3 are threaded to Aadjustably support arms G, G by the use of sets of nuts G2, G screwing on the threaded ends B4, B5. The arms G and G are connected with the outer ends of slides H, H mounted to Slide in suitable hearings H2, H3 arranged on the top of the measuring receptacles A, A. The inner end of the slide H is pivotally connected with a toggle lever consisting of the arms l, I', l2, I3, of which the outer ends of the arms Llare pivotally connected with the slide H and the arms I and I2 are pivotally connected with each other and the arms I and I3 are pivotally connected with each other. The inner ends of the arms I2, I2 are loosely fulcrumed on the stem C of the valve C (see Figs. 1 and 2), and on the said arms I2, I2 are pivoted pawls J, J engaging the teeth of a ratchet wheel K attached to the valve stern C. The pawls J and J are so arranged that when the toggle lever opens on the inward movement of the slide H then the pawl l turns the ratchet wheel K, while the pawl J glides over the teeth of the ratchet wheel, and when the toggle lever closes on the outward movement of the slide H then the pawl J turns the ratchet wheel K while the pawl J glides over the teethl of the ratchet wheel. Similarly a toggle'lever connection is made between the slide H and the ratchet wheel K, that is, the inner end of the slide H is pivot-ally connected with arms I4, I, pivotally connected with arms I, I7 loosely fulcrumed at their inner ends on the valve stem C. The arms 1 and I" are provided with pawls J2, J8 arranged in such a manner that when the toggle lever moves into open position on the inward movement of the slide H then .the pawl J2 turns the ratchet wheel K while the pawl J2 glides over the teeth of the said ratchet wheel. When the toggle lever closes on the outward movement of the slide H then the pawl J2 turns the ratchet wheel K while the pawl J3 glides over the teeth of the said ratchet wheel.

From the .foregoing it will be seen that the reciprocating motion of either piston B, B causes a continuous rotary motion of the valve C, that is, the latter is turned in theA direction of the arrowai.

The valve stem C is connected by suitable gearing L with a register-'N of any approved construction andarranged to indicate'the amou'nt of liquid measured in gallons, quarts and pints or other suitable standard of liquid measure (see Fig. 9).

The operation is as follows: Presuming that the several parts are in the position shown in Figs. l and 3, and the faucet connected with the outlet pipe E is opened,

then liquid ente-ringl by way of the pipe E into the chamber D passes by way of the ports a, a into the pipe F3 and into the outer end of the measuring receptacle A to force the piston B therein inwardly in the direction oi the arrow sa (see Fig. 1). The liquid contained in the inner end of the liquid measuring receptacle A passes by way of the pipe F2 and the port o into the outlet chamber D2 from which the liquid passes by wayof the pipe E and its faucet into a glass or other vessel to be filled. During the inward movement of the piston B in the direction of the arrow a2 the valve C is turned in the direction of the arrow by the action above described between the valve stem C and the piston B. At the time the piston B nears the end of its inward stroke the ports a and a are disconnected from the chamber D and the pipe F3 respectively, and the port is disconnected from th`e pipe F2, and at this time the port a3 connects with the chamber D while the port a2 connects with the4 pipe F so that the liquid Hows from the chamber D by way of the said ports a2, a2 and the pipe F into the outer end of the measuring receptacle A connected by its pipe F with the port b2, so that the liquid flows into the outer end of the measuring receptacle A and out of the inner end by way of the pipe F and the port b2 into the chamber D2 and. to the pipe E and out of the faucet thereof into the glass or other vessel to be filled. It is understood that the liquid fiowing into the outer end of the measuring receptacle A forces the piston B therein in an inward direction to insure a further rotation of the valve C, and at the time the piston B nears the inner end of its stroke the valve C has been turned suiiciently to connect the port 'a with the pipe F2 to direct the liquid into the inner end of the measuring receptacle A', the outer end of which is now connected by the pipe F3 and the port b with the outlet chamber D2. The ort a3 is still in communication with the c amber D sb that the liquid can How from the latter by wayof the ports as, a

into the pipe F2 and into the inner end of the measuring receptacle A to push the piston B outward therein. When the piston B nears the outer end of its stroke the valve C has been turned sufciently to move the port a2 into register with the pipe F so that the liquid can now iow from the cham* ber D by way of the ports a3, c2 and pipe F into the inner end of the measuring receptacle A to push the' piston B outward thereincassi in. The outer end of the measuring receptacle A is now connected by the pipe F with the port b to allow the liquid to flow' from the outer end of the measuring recepf tacle A into the chamber D2 and to the pipe E having the withdrawing faucet.

From the foregoing it will be seen that as long as the faucet is open liquid flows in a continuous stream through the liquid measuring device, and the rotation given to the valve C as above described causes an actuating of the register N which registers t-he amount of liquid drawn out of the container during the time the taucet is open. As soon as the faucetis closed the operation of the liquid measuring deviceceases, but as soon as the faucet is opened again a continuous flow of liquid is had, and the amount of liquid withdrawn is registered by the register N. It will be noticed that by the arrangement described an accurate tally is had on the amount of liquid periodically withdrawn from the container.

It is understood that beer and other liquids contained in barrels are usually under pressure and consequently iow readily through the measuring device to the dispensing faucet, but in case no pressure is on the liquid in the container then the liquid measuring device is located sutiiciently below the container so that the head of the liquid provides suicient pressure to actuate the device as above explained.

ln the modified form disclosed in Figs. 8 and 9 the measuring receptacles are in the form of two bellows A2, A2, connected at their fixed ends with the pipes F, F and F2, F3 leading to the valve casing D containing a valve C of the same construction as above described in reference to Figs. l to 7. Movable heads or pistons B, B7 are arranged in the bellows A2, A2 and are provided with arms G4, G5 connected with the toggle levers formed ofthe arms l, l', I2, I2' and I4, I5, I, I7 and pawls J, J', J2, J3 With the ratchet wheel K secured on the valve stem C for turning the valve C. The outletl pipe E' in this case connects with an apertured lug 0 secured into the bunghole of the container. |The operation is practically theends of the bellows A2, A3 causes the pistons- B6, B7 to reciprocate to turn the valve C in the same way as above described. As the amount of air passing into the container by way of the liquid measuring device is the same as the amount of liquid withdrawn therefrom it follows that the amount registered at the registering end indicates the amount of liquid withdrawn from the container.

Having thus described my invention, I claim as new and desire to secure by -Letters Patent:
